which is more efficient? ball bearing or ceramic pulley?

Ceramic bearings usually are lighter with less friction and rolling resistance.

Yes, like Tri said, it has one less ball bearing. It's pretty much the same otherwise. :)

I had bad luck with bones reds, had to return them twice because of some grinding issue, then got some super reds worked perfectly and runs extremely smooth especially if you clean and lube them on occasion. If you would want to go the cheaper route you have the possibility of getting a few bad bearings vs paying a little more getting better quality. as for which ones last longer I do not know.

The spindle with single pulley comes with pulley, the double pulley does not come with pulleys.

Synthetic rope is the only way to go. They even make ones that are short just for plowing. Going over the pulley so many times with a steel cable makes them break very fast. Synthetic is way more flexible and still strong. Pay close attention to where that cable travels when it's tight. Mine rubbed on a metal edge that I had to grind down so it didn't cut into the synthetic.

Check out the Required Items tab at this link http://www.tamiyausa.com/product/item.php?product-id=58346 Incidentally a ball bearing kit isn't "required". The kit comes with plastic bushings but a ball bearing kit will improve longevity, speed and battery life.

While its a lot more work it does a far better job than the simple pull behinds I've used that just have metal spring fingers sticking out.

There is a significant difference. Run time seems more than double. There seems to be more power. I've drilled a series of 4" deep holes in masonry with a 5/8 in bit and through 3/8" steel with a 3/8" bit. The impact driver runs a large part of a day hanging drywall or steel studs. I have both the older brushed and brushless tools. I would buy more brushless tools as they become available. As I've only used the brushless tools for a year but would assume that fewer moving parts would last longer. About the only repair to an electric motor today is brush replacement.

I recommend a low RPM motor that has a 5/8 shaft with keyway. You can get 5/8 bore pulleys at a hardware store. You may have to order the pulley that goes on your mill since I could not find that size at the store. My system is configured with a 5" pulley on the motor and a 3" pulley at the mill with a 30" belt to get an RPM from 83 to 133. Your motor doesn't necessarily have to be that low of RPM but you do want to crush your mill any higher than 200RPM. I spoke to Todd Millar, the inventor of this product and he recommends no more than 200.

This pulley is cast aluminum if this is for a gas engine I think you want Cast Iron to steel

Yes, the bearing is already pressed into the pulley. This was a cheap fix that worked well if your clutch has gone out. Getting the recessed snap ring back on that holds the electromagnet on was tedious bit doable. Need good pair of large snap ring pliers.

The only difference is one is very slightly larger. If one of the ball locks fits very tight , it uses the other. Hope this helps.

really couldnt say since i,ve never used a pulley machine,the unit i bought is still holding up to hard use,i,d ask a trainer that knows a little about rowers

Durability and weight. However, I usually find the nylon pulley wheels wear before the bearing condition really matters.

The difference is ball bearing, or (cartridge bearing) is the outer race is pressed into the pulley and the inner race rotates and is held in place with steel balls. Ceramic is similar, as the outer race is pressed into the pulley, but the inner race is machined to a close fit and rotates inside the outer race. All ceramic bushings I have seen are white, and look like white plastic, but is very hard. The actual pulley function is not affected by the type of bearing.

I haven't had any trouble with this tool. Pulls the different type of bearings that i use.

The synthetic cable works best. Easier and safer. Pulley can come in handy depending on what you plans are.
